[산업상 이용분야][Industrial use]

본 발명은 잉크젯 프린팅 방식의 칼라 레지스트에 대한 용해 특성이 우수한 씬너(thinner) 조성물에 관한 것으로서, 더욱 상세하게는 액정표시장치용 칼라필터의 제조과정에서 기판 위에 오형성(誤形成)된 칼라 레지스트 패턴을 용해시켜 쉽게 세척할 수 있을 뿐만 아니라, 잉크젯 프린터의 헤드 노즐에 대한 세정성능이 우수한 칼라 레지스트 씬너 조성물에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thinner composition having excellent dissolution properties in color resists of inkjet printing, and more particularly, to a color resist pattern misformed on a substrate during manufacturing of a color filter for a liquid crystal display device. The present invention relates to a color resist thinner composition which can dissolve and be easily washed and has excellent cleaning performance with respect to the head nozzle of an inkjet printer.

[종래 기술][Prior art]

액정표시장치용 칼라필터는 기판 위에 형성된 블랙 매트릭스 및 매트릭스 내부에 형상되는 칼라 레지스트(적색, 녹색 및 청색 패턴)를 포함한다.The color filter for a liquid crystal display device includes a black matrix formed on a substrate and color resists (red, green and blue patterns) formed in the matrix.

상기 칼라 레지스트를 형성시키는 방법으로는 안료 분산법, 염색법, 전착법, 잉크젯법 등이 주로 이용되고 있다. 그 중, 안료 분산법은 광 경화성 수지조성물에 안료를 분산시킨 칼라 레지스트 조성물을 이용하는 방법으로서 미세 패턴을 구현할 수 있으므로 가장 널리 사용되어져 왔다. 하지만 TV와 같은 색재현률(NTSC대비 색농도)이 높으며 대형 기판에 진행되어져야함에 따라 코팅 및 현상 공정에서 얼룩등의 큰 문제를 야기시켜 공정관리가 어렵게 되어왔다. 따라서 공정을 단순화하며 대량생산에 적합한 잉크젯 프린팅 방법을 이용한 컬러필터제작이 개발되어 양산화되고 있으며 잉크젯 잉크조성물에 대한 특허도 공개특허 05-40511호 및 출원특허 2004-108138 등에서 알려져 있다. 한편, 상기 잉크젯 프린터를 이용하는 기술로는 크게 두 가지로 버블젯 방식(bubble-jet type)과 압전소자 방식(piezo type)으로 나눌 수 있다. 그 중, 상기 버블젯 방식은 전기 열판에 전기를 가하여 열을 발생시키고, 그 열에 의해 수용성 잉크 내에 산소 기포가 발생하여 잉크를 밀어내는 원리를 이용한 것이다. 또한, 상기 압전소자 방식은 세라믹 압전소자에 전기를 가하여 압력을 발생시키고, 그 압력을 이용하여 잉크를 밀어내는 원리를 이용한 것이다.As the method for forming the color resist, a pigment dispersion method, a dyeing method, an electrodeposition method, an inkjet method, and the like are mainly used. Among them, the pigment dispersion method has been most widely used because it can implement a fine pattern as a method using a color resist composition in which a pigment is dispersed in a photocurable resin composition. However, as the TV has a high color reproduction rate (color density compared to NTSC) and needs to be progressed on a large substrate, process management has become difficult because it causes big problems such as stains in coating and developing processes. Therefore, color filter manufacturing using inkjet printing method suitable for mass production is simplified and mass-produced, and patents for inkjet ink compositions are also known in Korean Patent Application Publication Nos. 05-40511 and 2004-108138. On the other hand, there are two technologies for using the inkjet printer, which can be divided into a bubble-jet type and a piezo-type. Among them, the bubble jet method uses the principle of generating heat by applying electricity to the electric hot plate, and generating oxygen bubbles in the water-soluble ink by the heat to push the ink out. In addition, the piezoelectric element method uses a principle of generating pressure by applying electricity to the ceramic piezoelectric element and using the pressure to push ink out.

그러나, 상기 버블젯 방식은 젯팅(jetting)시 고온을 발생시켜야 하기 때문에 프린터 헤드의 가열부에 칼라 레지스트 잔류물이 형성되며, 상기 압전소자 방식 은 점도가 높은 수성 또는 유성 잉크를 사용하기 때문에 헤드 노즐에 칼라 레지스트 잔류물이 형성되어 노즐이 막히는 등의 문제가 발생하게 된다.However, since the bubble jet method needs to generate a high temperature when jetting, color resist residues are formed at the heating part of the print head, and the piezoelectric element method uses a high viscosity aqueous or oily ink head nozzle. Color resist residues are formed in the nozzles, causing problems such as clogging of the nozzles.

한편, 상기와 같은 칼라필터의 제조과정에서 생기는 불량은 대부분 패턴의 부분적 뜯김, 선폭 확대, 블랙 매트릭스와의 정렬(Align)불량등에서 기인하는 것으로 이미 경화된 칼라 레지스트는 잘못된 부분만을 제거하는 것이 거의 불가능하기 때문에 불량인 칼라필터는 대부분 폐기 처리되거나 재생을 위해서는 KOH, TMAH등의 강한 알칼리를 이용한 재생방법들이 알려져 있다. 하지만 잉크젯 프린팅 방식에서는 블랙 매트릭스내에 잉크가 정확히 젯팅이 되면 대부분의 불량은 해결이 되며 젯팅이 잘못된 경우 경화되기 이전에 쉽게 재생이 가능하다. 따라서 잘못 젯팅된 기판을 재생하고 잉크젯 헤드의 세척을 위해서 잉크젯 잉크와의 용해성이 우수하며 프린터 노즐과의 화학적 반응이 발생되지 않는 씬너 개발에 대한 필요성이 대두 되었다. On the other hand, defects in the manufacturing process of the color filter as described above are mostly due to partial tearing of the pattern, line width, alignment misalignment with the black matrix, it is almost impossible to remove only the wrong part of the color resist already cured. Therefore, the defective color filter is mostly discarded or regeneration methods using strong alkalis such as KOH and TMAH are known for regeneration. However, in the inkjet printing method, when the ink is jetted correctly in the black matrix, most defects are solved, and when the jetting is wrong, it can be easily regenerated before curing. Therefore, there is a need to develop a thinner that has excellent solubility with inkjet inks for regenerating misjeted substrates and cleaning the inkjet head, and does not cause chemical reaction with the printer nozzle.

상기와 같은 종래 기술의 문제점을 고려하여, 본 발명의 목적은 액정표시장치용 칼라필터의 제조과정에서 기판 위에 오형성된 칼라 레지스트 패턴을 용해시켜 쉽게 세척할 수 있을 뿐만 아니라, 제조과정에 사용되는 잉크젯 프린터의 헤드 노즐을 쉽게 세정할 수 있는 칼라 레지스트 씬너 조성물을 제공하는 것이다.In view of the problems of the prior art as described above, an object of the present invention is to dissolve the misaligned color resist pattern on the substrate in the manufacturing process of the color filter for the liquid crystal display device, and to easily wash the inkjet used in the manufacturing process. It is to provide a color resist thinner composition that can easily clean the head nozzle of the printer.
